Abstract

A method is provided which bonds a composite abrasive compact (10, 12) to cemented carbide pin (14). The method includes the steps locating a braze alloy (16) having a perforated metal material (20) embedded therein between a surface (22) of the composite abrasive compact (10, 12) and a surface (18) of the cemented carbide pin (14). The braze alloy (16) has a melting point below that of th metal material (20). The surfaces (18, 22) are urged together, the temperature of the braze alloy (16) is raised to above its melting point and maintained at this temperature for a short period. The alloy (16) is then allowed to cool and solidify and bond the surfaces (18, 22) together.
